If it gets really red, swollen & puffy.. It would be the size of a quarter and look almost like an allergic reaction. If you don't have TB there will just be a little red spot and barely visible.
I Just Had A TB Test Shot Monday, And I Forgot To Go Get It Checked Today. How Can You Tell If You Have The TB?
Krystald30 is 100%spot on. And the next step to tell for sure would be a chest x ray. But no reaction from the shot, no TB.
The bubbles don't go off. Well the real answer will be to go and get it checked again and come back when you were ask to come back for it to be checked out.
